Abstract
There is an increasing need for high resolution spectroscopic measurements in areas such as gas phase molecular studies, low temperature matrices and solid state physics and environmental air analysis. In order to meet this demand, a very high resolution Fourier transform spectrometer, the IFS 120 HR has been developed which can operate from the far infrared to ultraviolet spectral ranges. The instrument incorporates a number of novel design features to enable the recording of spectra with excellent signal to noise ratio in short measurement times, high resolution achieving line widths of 0.0014 cm-1 (width at half height of CO absorption lines in the far infrared) and accurate lineshapes. Various data handling routines have been added tailored for the special requirements of high resolution spectroscopy including an extended plot package, automatic peak finder and post transform zero-filling for spectral interpolation. The poster will describe the instrument in detail and present example spectra from various fields of application.
